DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 394,709, dated December 18, 1888. Application filed September 7, 1888- Serial No. 284,789. (No model.)

To all 2071 0722, it only concern:

Be it known that I, BENJAMIN A. MI'rcHELL, Jr., a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsyhania, have invented a new and useful Improvement in Door Checks or \Veights, which improvement is fully set forth in the following specification and accompanying d rawi 11 My invention relates to improvenn-mts in door checks or weights, and has for its object to provide a simple and inexpensive device of the character mentioned which will retain the door in any open position.

The invention consists of a door check or weight formed of a yoke-shaped piece of material, with means for holding the yoke in position on the door and preventingthe rattlin or shaking oi the parts in contact.

Figure i represents a perspective view of a door check or weight embodying my invention in position, a door being shown in dotted Fig. 2 represents a top plan view thereof, partly broken away.

Similar letters of reference indicate corresponding parts in two figures.

Referring to the drawings, A designates a yoke or U-shaped piece of metal or other suitable material, which isprovided with supportinglegs 13, which, however, may be dispensed with and the yoke rest directly on the floor.

C designates springs secured to the inner opposite sides of the yoke, and to said springs are attached plates I), provided with pins E, which are adapted when the plates are pressed in to enter sockets F in the yoke, and thus serve to guide the plates.

The operation is as follows: \Vhen it is desired to check or retain the door open, the yoke is applied to the door so as to cause the plates to press against the same, due to the action of the spring, thus preventing the yoke from displacement and the door from rattling,

the yoke, as is evident by its weight, holdingthe door in the desired open position.

In some cases the plates D and pins E may be dispensed with, in which case the door is directly in contact with the springs.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A door-check consisting of a piece of rigid and weighted material adapted to rest on the floor and movable thereon under pressure, and a spring secured to said weighted piece adapted to embrace thedoor and to hold it in fixed position,said parts being combined substantially as and for the purpose set forth.

2. A door check or weight consisting of a yoke adapted to rest upon the floor, and having a spring pressing against the door to retain the device and door in the desired posi tion, substantially described.

3. The herein described door check or weight, consisting of the yoke having sockets in its inner sides and spring-plates attached to said yoke, and having guiding-pins which enter said sockets, substantially as described.
